瑞銀完成了其UBS Key4黃金產品的概念證明，以太坊層網絡ZKSYNC

該模擬是在ZKSYNC測試網絡上進行的，是傳統金融機構中對區塊鏈技術的重新興趣的跡象。

Swiss banking giant UBS has completed a proof-of-concept of its UBS Key4 Gold offering on the Ethereum layer-2 network ZKsync.

瑞士銀行業務巨頭瑞銀（UBS）已經完成了以太坊2層網絡ZKSYNC上其UBS Key4 Gold產品的概念驗證。

The simulation, which was conducted on a ZKsync test network, is a sign of renewed interest in blockchain technology among traditional financial institutions.

該模擬是在ZKSYNC測試網絡上進行的，是傳統金融機構中對區塊鏈技術的重新興趣的跡象。

This isn’t UBS’ first experiment with blockchain. The bank previously launched a tokenized money market investment fund, uMint, which is also built on Ethereum.

這不是UBS對區塊鏈的第一次實驗。該銀行此前啟動了一個令牌化的貨幣市場投資基金Umint，該基金也建立在以太坊上。

UBS’ Key4 Gold is one of the bank's offerings that lets its Swiss clients purchase a direct claim to physical gold. “It allows for fractional gold investments with real-time pricing, deep liquidity, secure physical storage, and optional physical delivery,” the team said in a press release shared with CoinDesk.

瑞銀（UBS）的Key4 Gold是該銀行的產品之一，可讓瑞士客戶購買直接索賠實物黃金。該團隊在與Coindesk共享的新聞稿中說：“它允許具有實時定價，深厚的流動性，安全的物理存儲和可選的物理交付的分數投資。”

The project already exists on the bank's private blockchain, the UBS Gold Network, but the team was looking for ways to scale its project while preserving its privacy. “They came to the conclusion that only zero-knowledge made sense for them, and so they wanted to really put this in practice for a product that they already have live and what this could look like if they use the validium instead,” Pearl Imbach, a Senior Business Development Manager at Matter Labs, the main developer firm behind ZKsync, told CoinDesk in an interview.

該項目已經存在於銀行的私人區塊鏈，瑞銀黃金網絡上，但是該團隊正在尋找在保留其隱私的同時擴展其項目的方法。 “他們得出的結論是，只有零知識對他們來說是有意義的，因此他們想真正將其付諸實踐，以便將其用於已經存在的產品，如果他們使用有效量，這將是什麼樣子，” Pearl Imbach ZKSYNC背後的主要開發人員公司Matter Labs的高級業務開發經理在接受采訪時告訴Coindesk。

ZKsync is a zero-knowledge rollup, a type of layer 2 scaling system that aims to increase the speed of blockchain transactions and reduce their fees, by using zero-knowledge cryptography. A validium is a different type of layer-2, similar to that of a rollup, but stores the data of those transactions off-chain.

ZKSYNC是一種零知識匯總，這是一種類型的2層縮放系統，旨在通過使用零知識加密術，旨在提高區塊鏈交易的速度並降低其費用。有效量是一種不同類型的第2層類型，類似於匯總，但將這些交易的數據存儲在鏈上。

The test transaction may signal that UBS could be looking more closely at using layer-2 technologies to power some of its activities. However, the bank didn't say whether they would come out with their own layer-2, and Matter Labs' Imbach told CoinDesk that a rollup might not be the right fit for them. “Is this the right product [for UBS]? Perhaps not, but it is something we're just talking openly about, and thinking about what could actually be a good use case for them,” Imbach told CoinDesk.

測試交易可能表明瑞銀可能會更仔細地考慮使用2層技術為其某些活動提供動力。但是，銀行沒有說他們是否會出現自己的2層，而物質實驗室的Imbach告訴Coindesk，滾動可能不適合他們。 “這是[瑞銀]正確的產品嗎？也許不是，但這是我們只是公開談論的事情，並想到實際上可能是一個很好的用例，” Imbach告訴Coindesk。

This isn't the first time a banking giant has used ZKsync's technology for its own products. Deutsche Bank said in December that it was also planning to build a layer-2 with ZKsync’s technology, indicating how blockchain technology can co-exist or even make traditional financial institutes' products work better.

這不是銀行巨頭第一次將ZKSYNC的技術用於自己的產品。德意志銀行在12月表示，它還計劃使用ZKSYNC的技術建立2層，這表明區塊鏈技術如何共存，甚至可以使傳統金融機構的產品效果更好。

“What we are offering now, with privacy on top [of the blockchain] is something that is super interesting, and we're doing more and more of these use cases now,” Imbach told CoinDesk.

Imbach告訴Coindesk：“我們現在提供的是非常有趣的（區塊鏈）的私密性，現在我們正在做越來越多的這些用例。”
